Some items in Favorite Folders disappear when starting Outlook

[Jan]

I have several folders in Favorite Folders including Unread Mail and Junk
E-Mail. All was fine until recently, now every time I start Outlook 2007
the Unread Mail and Junk Mail folders disappear from Favorite folders, all
others remain.

Is there a way to prevent this happening?

Sounds like you have a corruption in your Navigation Pane. Reset it via;
Start-> Run; outlook.exe /resetnavpane
